JavaScript Data Access Test

The purpose of this page is to determine the performance issues related to data access
in JavaScript. In all browsers, literal values and local variables are faster to access than
object properties and array items. The difference between object properties and array items
varies by browser.

The tests on this page access each location a set number of times. That is repeated 100 times and the
average time is reported. I also test property depth, so object.property versus
object.property.property is validated. The tests may take several minutes to fully execute
but should not crash the browser.
